This page is designed to allow individuals and
entities interested in obtaining Illinois
discharge data for a variety of purposes the means
to start the data acquisition process. This site
contains information on both inpatient and
outpatient data available for a wide range of uses
including but not limited to research, commercial
health care operations, graduate thesis
preparation and support for grant development.

The data available varies by service type and
discharge year, with historical discharge data consisting
of inpatient data from January of 1987 and
outpatient surgical data starting with discharges
occurring in January of 2002. These data are based
on the national standard Uniform Bill (UB) with the
associated periodic enhancements.

Starting in 1987 with the UB82, the collection
system was updated in 1993 with additional
elements from the UB92. Data beginning with
discharges occurring in October of 2007, elements
from the UB04 were incorporated and remain the
basis of current data collection efforts. Beginning
with 2009 data, additional data elements and
outpatient emergency
department and observation care data are now
available along with outpatient surgical data from
acute care hospitals and ambulatory surgical
treatment centers (ASTCs).

Release of data
requires application approval, signed data use
agreement and payment
of the necessary
fee based on data usage and entity category.
Contacts for data request/application vary with
the type of applicant and intended usage.
Representatives of the Media should contact the
IDPH Public Information Office, while all other
requestors/applicants should contact the program data
steward.
